IMPALA-9129: Add a test fixture that cleans up intentional core dumps

Some negative tests produce core dumps intentionally. We should have a
way of removing these as part of test cleanup.

For custom cluster tests, it's likely the cores may actually be generated
during the base class setup phase, which means it's too early for the
test fixture to really be useful. Such was the case with the test case
TestAuthorizationProvider::test_invalid_provider_flag. In this instance,
we had to add the same steps directly to the tests.

Testing done:
For test_invalid_provider_flag, I made sure I had pre-existing core files
in the IMPALA_HOME directory, then ran the test to confirm new cores were
removed.

...and then made sure the pre-existing cores were still present.
